You trust a closed source OS from a developer already proven to be willing to engineer backdoors and lie about it over an open-source OS? Can you explain your reasoning?

I don't actually _trust_ either one, but I would certainly rank Windows below Linux.

Also note that the linux runtime in Win10 is not installed or activated by default; you need to put the OS in developer mode and install it yourself. If an attacker can do that externally, he already owns your system.
